FABRIC BINDING STRIP.

Application filed February 12, 1323, Serial No. 618,590.

To (2Z1 wiiomit may concern:

Be it lrnown that 1, Auto FREYDBERG, a citizen of the Tinted States, and resident of Mount Vernon, in the count) of 5 Vestcnrster and ate of Few York. have invented certain w and useful Improvements in Fabric 1 riding Strips, of which is a s ecification.

tes to fabric binding d for melting bindings inents. and more peril lOliES-Pllij, fest-edged binding of S"li binding material.

rig strips, that is to say, e threads of the fabric run at right angles to the longiedges of the strip, are often used,

are relatively free from a tendel at the edges; but such strips desirable as bias-cut strips in "e threads'run diagonally in relalongitudinsl edges because these ips are more readily shaped and seal to curved portions or corners or" iubric structures to which These hiss-cut -vei or split inward from TOZ'Q freely than the S and for that reason have wid invention r s"' i as are er than would otherwise he order to provide wider inerie or less reveled edges outbu ate this difficulty myinvention s novel fast-edged bias-cut hindsap or roll of such material, the fasteling consisting specifically in adhesive material applied to the edges of the strip i and more particularly, applied to the faces of s roll formed of such a strip so that the adhesive adheres to the strip edges. when the strip is run 05 the roll for use, and prevent rsveling so that the strip may be made of practically any desired width, and es pecie .y may he made as narrow as may be desired for any particular purpose, without eliowance for raveling; and the firm edge also permits the binding to run more freely and accurately through the binding mech-. anism of sewing machines.

The method of production of the strip or strip roll takes into consideration the tendency of bias-cut strips to stretch longitudinally under moderate tension, and at tfne same time to contract laterally. The

. proper lug, when the bindings are method of producing and fast-edging the strip or strip roll avoids or reduces such distortion of the strip.

The method, generally described, comprises cutting a wide piece of suitable stripforining fabric diagonally to form pieces of suitable length, sewing together the selvage edges of these pieces to produce 2 wide strip in wh h the fabric threads run diagonally i n to the longitudinal edges, rollon a suitable core such as c d t be, severing the complete roll consisting of the fabric and the core at regular intervals to produce relatively narrow individual rolls of binding 'strip of t ,e width for the purpose in View, and applying adhesive such as a suitable glue to hoth feces of the individual rolls whereby all e {he edges of the strip are fastedged l me in roll form, this adhesive adheri'n I to the edges of the strip when it is pulled of? or the roll and preventing ravel in; and also tending to prevent stretching and improper distortion of the strip as it is insniou ed applying it to garments and other ieurics.

The characteristics and advantages of the invention are fu h r sufiiciently explained in connection wi' he following detail de scription of the accompanying drawings "which show e representative embodiment, of the binding strip or roll and also illustrate one performance of the production method, After considering these exempliiicetions the invention persons skilled in the art will understand that many variations, may made, and I do not limit myself to details except as claimed.

Figure 1 shows a strip of full width fabric and the manner of cutting it diagonally to form individual, wide, bias-cut pieces.

Figure 2 shows the manner of connecting these pieces to form a wide strip or web and of rolling this web to produce a long roll.

vl igure 3 is a plan view of the long roll, illustrating'the manner of cutting or severing it to produce individual binding strip rolls.

Figure at illustrates one manner of fastin ress strip-forming fabric F. Suitable lengths of the fabric are run off of the rolls or bolts and a plurality of these pieces may be superposed; butregardlcss of the manner of cutting up the full-Width. cloth, the fabric l is cut diagonally along the lines 7; producing individual pieces P in which the Warp and wool threads run diagonally or in bias relation to the edges The selvage edges (z of two these pieces I are brou ht together and stitched as a, igure 2, Iorrni g a wide strip or web V] t bias-cut material which is wound upon suitable core which is most conveniently a card board tube s, forming a long roll L of hiss-cut material.

This roll L is severed transversely at regular intervals as in the nlanes 76. Figure 3 4 producing individual rolls of bias binding material of desired 77 1' Adhesive or a suitable ha acter such as a suitable glue is then applied to the edge faces of the rolls as sntliciently illus rated in Figure at. producing the COIHPlQiIQQl lastedged roll Figure 5. in which l cut edges of the rabrie in roll form are coated with the adhesive.

Figure 6 shows a length of the b' iding strip S pulled oil of the roll The edges ll are coated with a sufficient quantity of the glue applied While in the roll form to cause adjacent thread ends to adhere to each other and to completely or substantially prevent raveling. The strip isreally in separate pieces connected by portions or the seams s which were formed when the Wide bias pieces P were sewed together. These scams or connections are unobjectionable in the use of the bindin The strip has all the advantages of an ordinary biascut strip With the added important advantage of fast-edging, which prevents raveling, and causes the strip to run more smoothly and accurately through the SBWlIlg-fl&- chine binder mechanism, and with the fura new article of inanu'f comprising i 'laoric. said material ively narrow bias-cut- 1 i e i 1' i i' v onsisnng or a puma iny or intuit ell res-cu:- pieces joined together ines. the opposite longitudinal c I abric being" treated with adhesive ling tendency of the hHQHQS along; such roll and

3. As a new article or" manufacture a roll or binding material comprising a core and a length or" relatively narrow bias-cut binding fabric Wound thereon, said length consisting of plurality of relatively narrow bias-cut pieces joined together on diagonal lines, and the opposite faces of the roll heing treated with adhesive to retard the fraying tendency of the threads along the longitudinal edges of the fabric.
